VEHICLE-SPINDLE Specification of Letters Patent.

Patented July 28, 1908.

Application filed September 17, 1907. Serial No. 393,262.

To all whom it may concern:

Be it known that I, TRAVIS T. THOMPSON, a citizen of the United States,residing at Bogata, in the county of Red River and State of Texas, haveinvented certain new and useful Improvements in Vehicle-Spin dles, ofwhich the following is a specification.

My invention relates to that class of buggy, carriage and wagon axles,or axles of other light vehicles, in which the spindle of the axle isprovided with an adjustable and removable sleeve. This sleeve may beturned on the spindle from time to time, presenting new, unworn surfacesuntil worn out, and then it may be entirely removed and a new onesubstitutedin its place. Thus it will never be necessary, on account ofthe wear of the sleeve or spindle, to remove the axle, and thus greattime, labor and expense are saved.

In the accompanying drawings, Figure 1, is an elevation of my invention.Fig. 2, is a longitudinal view of my invention, the spindle being inelevation, the sleeve and nut in section.

In describing my invention I read the drawings from left to right.

My invention is described as follows In the accompanying drawings thenumeral 1, represents the axle; 2, the large shoulder; 3 the smallshoulder and 4, the spindle. This invention is applied toboth ends ofthe axle. Each end of the axle for some little distance, is providedwith a thread 5, and the large part 3 of the spindle is provided with athread 6, and the small part 4, of the spindle is also provided with athread 7. These threads all correspond with each other in thickness,depth and pitch, and are right and left.

A sleeve 8, whose inner surface "exactly corresponds with the outersurface of the axle and spindle just described, and whose inner surfaceis provided with threads which exactly correspond in thickness, depthand pitch with the threads on the axle and spindle just described, issecured on said spindle.

The large part 3 of the spindle and the enlarged part 6 of the sleeve,are for the purpose of strengthening the spindle at the point where itis likely to be worn most, and broken.

Screwing on the threaded end of the spin dle is a safety nut 9, havingan inwardly projecting rim 10. The purpose of this rim 10, is to form asmooth surface to fit against the outer end of the hub, and at the sametime leave an oil well 11.

The rear and flange part of the hub runs backwardly and fits over theintegral elevation 12, of the sleeve, which elevation 12, is providedwith an annular oil well 13. Said sleeve is also provided in its'largeand small parts with oil wells 14 and 15, respectively. There may bemore of these oil wells if desired. The rear part 16, of the sleeve issquare or octagonal, preferably octagonal, so that the sleeve can bescrewed on and off from the axle and spindle.

Screwing into perforation 16 in the rear 73 part of the sleeve and intorecesses 17 in the threaded part of the axle is a set screw 17,countersunk when screwed home. There may be several of these recesses 17around the threaded part of said axle. When the 75 sleeve becomes worn,on its under side, I loosen the set screw 17, and turn the worn part toone side, and then turn the set screw into another recess to hold .thesleeve in place, and when worn again I repeat the same operation untilall the annular surface of the sleeve has thus been gone over, and whenworn out I remove and replace it by a new one.

Having described my invention, what I 8 claim as new and desire tosecure by Letters Patent, is r 1. The combination of a vehicle axle,terminating at each end in a spindle, each end of said axle providedwith a thread 5, and each threaded portion with recesses 17 the spindleparts having large parts 3 each provided with a thread 6, and a smallpart 1, provided with a thread 7, all of said threads having the samepitch and being the same size, and sleeves 8, their inner surfacescorresponding to the outer surface of said axle and of said spindle, andhaving threads corresponding to said threads 5, 6 and 7, the spindlepart of said sleeves corres onding in shape to the spindles of said axe; integral enlargements 12, extending from the inner end of saidsleeves, each enlargement provided with an annular oil well; integralextensions extending from the rear part of said enlargements, andfitting over the threaded part of said axle, said extensions eachprovided with a screw-hole 16 substantially as shown and described andfor the purposes set forth.

2. The combination of a vehicle axle, ter- 119 minating at each end in aspindle, each end of said axle {provided with a thread 5, and

each threaded portion with recesses 17 the spindle parts having largeparts 3 each provided with a thread 6, and a small part 4, provided witha thread 7, all of said threads aving the same pitch and being of thesame size; sleeves 8, their inner surfaces corresponding to the outersurface of said axle and of said spindle, and having threads corresponding to said threads 5, 6 and 7, the spindle part of said sleevescorres onding in shape to' the spindles of said ax e integralenlargements 12, extending from the inner end of said sleeves, eachenlargement provided with an annular oil well; integral extensions,extending from the rear part of said enlargements and fitting over thethreaded part of said axle, said extensions each probetween the innerfaces of said rims anc the outer faces of said sleeves, substantially asshown and described and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.

TRAVIS T. THOMPSON.
